Modern homes are demanding more from their electrical systems than ever before. Between smart home devices, multiple-zone HVAC systems, and electric vehicle chargers, it’s no surprise that homeowners experience flickering lights, tripped breakers, or even damaged wiring.
One commonly overlooked culprit is how your HVAC system starts up. Unlike hard start kits, which increase startup torque, soft starters reduce electrical strain by controlling how power is delivered during startup.
In Florida homes, where HVAC systems run frequently and electrical demand is high, soft starters are becoming an increasingly popular upgrade.
Every time your air conditioner starts, its compressor draws a brief but powerful surge of electricity called inrush current. This surge is measured as Locked Rotor Amps (LRA), which represents the maximum current the compressor pulls when starting from a standstill.
LRA can be four to eight times higher than the unit’s normal running current, even though it typically lasts less than a second. You can usually find the LRA rating on your AC unit’s nameplate, which helps technicians understand the startup demands of your system. Homes with older electrical panels or frequent breaker trips may see even greater benefits from a soft starter.
Repeated “hard starts” over time can place stress on your home’s electrical system, including:
A soft starter is a device that reduces the sudden electrical surge when a compressor starts. Instead of drawing full voltage instantly, it gradually ramps up power, protecting both your HVAC system and your home’s wiring. Some soft starters also include surge suppression and voltage fluctuation protection, providing additional security for your home’s electronics.
Installing a soft starter can provide immediate, noticeable benefits:
While soft starters do not reduce the normal running energy of your AC, they cut peak demand at startup by up to 60-70 percent, which can reduce stress on your home and the grid.
Over time, this means:
A soft starter is more than just a technical upgrade; it’s a practical way to protect your home and your investment. By reducing the intense electrical surge when your AC starts, it helps prevent tripped breakers, flickering lights, and the long-term wear on wiring that can lead to costly repairs.
Softer startups also extend the life of your compressor and other HVAC components, saving you money on maintenance and replacements over time. Many homeowners notice that their system starts more quietly and smoothly, eliminating disruptive noises that can make even a new AC feel harsh.
Additionally, lowering peak startup demand can ease strain on your home’s electrical system and may reduce certain energy costs, giving you both immediate and long-term value. In short, a soft starter provides reliability, efficiency, and peace of mind, making it a smart choice for any home.
Soft starters do not reduce the normal running energy of your AC, but they significantly reduce peak electrical demand during startup. This can lower stress on your electrical system and may help reduce certain energy-related costs.
Flickering lights often occur because the AC compressor draws a large amount of electricity when starting. A soft starter reduces this surge, which can eliminate or greatly reduce flickering.
A licensed technician can evaluate your system, electrical panel, and startup load to determine whether a soft starter would provide real benefits for your home.
